Product Description:

Nut Coke with Low Phos


Main ingredients for FeS2, namely the ferrous sulfide, in which the mass fraction of Fe is about 46.5519684580%, copper pyrite because its yellow color and bright metallic luster, often mistaken for a gold.Crystal is a cubic system of sulfide minerals.The ingredients usually containing cobalt, nickel, and selenium, type with NaCl crystal structure.Very good crystal shape, a cube, octahedron, pentagonal dodecahedron and their combination.The cube on the face and crystal axial parallel stripes, all the stripes on the crystal plane perpendicular to each other.Collection is dense, lump or nodular.Black, green, yellow yellow (copper) color, stripe, strong metallic luster, opaque, no cleavage, jagged fracture.Mohs hardness is bigger, up to 6-6.5, knife carving.The proportion of 4.9 5.2.Under the condition of the surface weathering of limonite.

Q:Purpose of using coke in iron making raw materials
Purpose as follows:1. Provide the heat required for the reaction2, do reducing agent, generate CO, at the same time itself can also restore the iron
Q:What is the difference between coke and coking coal
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed coal gas producer with solid slag discharging. It is used as the raw material to produce CO and H2 gas
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
The use of coke:Shanxi sales of various specifications of foundry coke, metallurgical coke, high sulfur coke or motor transport cars can be. The specific indicators are as follows:More than 83 of the fixed carbon; sulfur below the volatile content of less than 1.5; ash around 15 e:Mechanism coke: used in metallurgy; steel plantFiddle coke size 8cm-150cm: of molten iron for casting {;} of motor shell, radiator, mechanical counterweightCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweightLarge modified coke: {for ordinary casting; mechanical parts such as rough parts for 2-3.5 tons of furnace type}The shape of coke size 25cm:{is used for ordinary casting and slightly rigid casting products, such as water pump pipe fittings, such as fire fastenerMore than 85 of the fixed carbon; volatile 1.5.; ash content of less than 13.5 sulfur; less than 0.5:A fiddle coke size above 8cm for ordinary casting: {}Setting coke size 25cm; {for precision casting and ductile castingImproved coke: (Jiao Meilian) {for precision casting and ductile castingCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweight
Q:The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,
Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
Q:How many degrees of coke ignition temperature can ignite coke
The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;
Q:How much coal can a kilogram of coal weigh?
But now the coking industry will not only coke coke, but with coking coal, fat coal, gas coal and other coal mixed coking
Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
2, gasification coke, is dedicated to the production of coke gas, mainly used for solid slag in the fixed bed gas producer, as a gasification raw material, the production of CO and H2 as a combustible component of the gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block proper and uniform.
Q:How to calculate the average particle size of coke
That is, "(volume) of the table of the percentage, in addition to the corresponding boundary value", these values are added, then the countdown. For example, the boundary 0 to 1 has a value of 10%, between 1 and 2, and between 2 and 4 has a value of 40%, and between 4 and 8, then D (3,2) = / (0.1/0.5 + 0.3/1.5 + 0.4/3 + 0.2/6) = 1/ (+ + 0.2 + + + 0.13 + +) = 1/0.56 = = =
Q:How coal is turned into coke in the coking chamber
The kiln chamber wall set to continue burning, and some heat incoming kiln (indirect heating). High temperature gas flow (800 DEG C, is mixed with coal pyrolysis, chemical products into the fabric of unburned.
Q:Types of coke and use of coke
Generally speaking, the use of coke in the following industries: blast furnace ironmaking, mechanical casting, calcium carbide production, processing Ferroalloy, chemical fertilizer, gas and high-tech high value-added industries
